1937c. First records of the smelt, Osmerus 

 mordax, in Lake Erie. Copeia 1937(1): 

 64-65. 



Record of first smelt identified from 

 Lake Erie, captured off Vermilion, 

 Ohio, June 30, 1936, and review of 

 several earlier and later reports of 

 smelt indicating firm establishment of 

 the species in the Lake.

1937d. The age, growth, and sex ratio of the 

 Lake Superior longjaw, Leucichthys 

 zenithicus (Jordan and Evermann). Pap. 

 Mich. Acad. Sci. Arts Lett. 22:691-711. 



Life-history study giving data on 

 age and size distribution, growth in 

 length and weight, growth compensa- 

 tion, sex ratio, length-weight relation, 

 and condition (a negative correlation 

 demonstrated between the growth rate 

 and condition of individual fish). Pro- 

 tection of longjaw to end of sixth year 

 of life (total length, about 10.3 inches) 

 is advocated.

1937e. The dispersal of smelt, Osmerus 



mordax (Mitchill), in the Great Lakes 

 region. Trans. Amer. Fish. Soc. 66: 

 160-171. 



Record of plantings of smelt in the 

 Great Lakes and a year-by-year ac- 

 count of the spread of the smelt through 

 Lakes Michigan, Huron, Superior, and 

 Erie.

1937f. The Great Lakes fisheries: their 

 proper management for sustained 

 yields. Trans. Amer. Fish. Soc. 66: 

 131-138. 



Reconnmendations of seven- point 

 program of regulation and research: 

 centralized control and discretionary 

 power; complete statistics properly 

 analyzed; research on causes of fluctu- 

 ations in abundance and yield; identifi- 

 cation of races and studies of migra- 

 tions; experimental investigations of 

 gear; evaluation of artificial and natural 

 propagation; and control over introduc- 

 tions of exotic species,

1937g. The North Central States Wildlife 

 Conference. Progr. Fish-Cult., Memo. 

 1-131, No. 26:15-19. 



Review and evaluation of papers and 

 discussions at the conference on such 



questions as: methods and values of 

 surveys; fish populations of "type" 

 waters and limitations of the type- 

 water concept; effectiveness of arti- 

 ficial propagation and environmental 

 improvement.

1938a. From cisco to perch to pike. State 

 Govt. ll(3):55-57. 



Review of decline of production of 

 selected species in certain lakes with 

 emphasis on the progressive nature of 

 depletion in the Great Lakes, shown 

 especially by deterioration of average 

 quality of the catch as fishermen turned 

 to cheaper species after depleting the 

 stocks of the more desirable varieties.

1938b. Michigan's commercial fisheries of 

 the Great Lakes. Mich. Hist. Mag. 

 22(l):3-39. 



Review of fishery from earliest to 

 modern times with respect to fishing 

 grounds, boats and gear (construction 

 and operation of different types de- 

 scribed), and trends of production. In- 

 cludes accounts of early statistical and 

 biological surveys and of modern re- 

 search programs and an analysis of 

 present-day problems of regulation and 

 management.

1938c. The age and growth of the Lake 

 Erie sheepshead, Aplodinotus grunniens 

 Rafinesque. Pap. Mich. Acad. Sci. Arts 

 Lett. 23:651-668. 



Life-history study includes data on 

 age and size composition, growth in 

 length and weight, growth compensa- 

 tion, length-weight relation, and con- 

 dition. The large size attained by some 

 sheepshead was shown to depend on a 

 long life.

 Great Lakes fisheries. Proc. Great 

 Lakes Fish. Conf., at Detroit, Mich.,

Presentation and discussion of 

 charts showing outstanding examples of 

 collapse in production in Lake Erie 

 sturgeon, Lake Superior whitefish, Lake 

 Huron yellow perch .... Stresses fallacy 

 of use of total production figures that 

 do not reflect progressive shift of 

 species composition from more valuable 

 to coarse varieties or show effects of
